Tension and bending fatigue tests were carried out to investigate the fatigue behavior of polymethyl methacrylate for edge attachment element at different temperatures.

For polymethyl methacrylate(PMMA),pure mode I fracture tests were performed under quasi-static loading by using central notched circular disk specimen.

Mechanical and optical functions of polymethyl methacrylate were analyzed in this paper.

Development of the aviation plexiglass drawing force digital PID control system;

Results indicate that plexiglass protective layers have better adhesion than silicate protective layers;with the increasing of temperature and holding time,adhesion of silicate protective layers is going up at first and then down,while that of plexiglass rises at first and then don't change;cooling mode has great influence on adhesion of silicate protective layers,while it has no impact on.

The result of the experiment shows that if add crosslinking TAIC and plasticizer phthalate to the ploymer,heat resistance and brittleness of plexiglass could be modified.
